I am working towards installing CM7 on my HTC Incredible and have hit a snag. When using 'Reboot into Recovery' from ROM Manager v4.3.3.0 the phone reboots into Recovery, but the menus do not function properly. I can scroll up and down with volume control, but pushing power to select an option blanks the menu and takes the watermarked Icon for ROM Manager at center of display and makes it solid with nothing else displayed. Action does not happen. If I press power again, it toggles back to showing the menu and I can scroll up and down, but no action can be selected. I have to take battery out to boot again. I thought it might be due to doing this first time with USB connected to computer since install guide states:

Known Issues

Shutting down the phone with USB plugged in will start ClockworkMod
Recovery in an unreliable mode.

Shutting down the phone and then plugging in USB will also start
ClockworkMod Recovery in an unreliable mode.

The HTC Battery charge icon is replaced by ClockworkMod. Charge with
the phone running in standby mode.

But upon retry without USB plugged in same result. I tried 'Flash Alternate Recovery' to "RA_GNM Recovery v2.2.1" in Rom Manager and it gets: "An error occurred while flashing your recovery." I tried 'All ClockworkMod Recoveries' to move back to v3.0.0.7 and then back to v3.0.0.8 and it still fails in same fashion.
